Tiny cavities in iron sulphide rocks
(these cavities played the role of cell boundaries; larger molecules accumulated since unable to pass through narrow pores)
External page: A very plausible theory of life's origin has emerged, solving many of the problems inherent in other hypotheses. Protons from seawater migrate to the alkaline pores, providing free energy; such proton transfers remain at the heart of living metabolism.
